Grain Boundary Energy from Experiment and Simulation
A collaboration between the CMU MRSEC and Sandia National Laboratory has permitted the first large scale comparison between experimentally measured grain boundary energies and energies calculated based on atomistic simulations. The techniques for the measurement (at CMU) and the calculations (Sandia) are unique to each institution and largest experimental and theoretical data sets currently available. The favorable comparison validates the methods.

High-entropy engineering of the crystal and electronic structures in a Dirac material
Quantum materials have the potential to revolutionize technologies ranging from sensing to telecommunication and computation. However, advancement has been limited by the development of topological and Dirac materials. IRG2 researchers demonstrated a novel and widely applicable strategy to engineer relativistic electron states to develop such materials through a high-entropy approach.

Crack Interaction With Microstructure: An in-situ TEM Study
Understanding crack growth behavior in complex materials is critical to material design for damage tolerance. An advancing crack, by virtue of its stress field, modifies the microstructure ahead of it including include changes in dislocation density, interfaces modification, decohesion of interfaces, void nucleation, and phase transformation . Such changes in microstructure can in turn have a reciprocal effect on the advancing crack. The problem is hierarchical in length scale and must be examined at the continuum, mesoscopic and atomic scales.

Cooking and Science: A Conversation on Creativity
With over 2 million requests annually for only 8,000 reservations at El Bulli, the renowned restaurant is harder to get into than Harvard. During his visit to the MRSEC in December 2008, El Bulli founder and globally celebrated chef, Ferran Adriàƒ’ , talked with students in the Innovations course, discussed ways of bringing Center research on soft matter to the development of new foods, and gave an enthusiastically received public lecture on the dynamic relationship between modern science and modern cuisine. His visit was covered by Time and the local news stations.

Interface-induced superconductivity in magnetic topological insulators
An IRG1 team employed molecular beam epitaxy to synthesize heterostructures stacking a ferromagnetic topological insulator with a quantum anomalous Hall state, Cr-doped (Bi, Sb)2Te3, and an antiferromagnetic iron chalcogenide, FeTe, with an atomically sharp interface. An unexpected phenomenon emerges: interface-induced superconductivity.

Portable Electron Microscope for K-12 Science Lessons
Graduate students at the University of Arkansas bring cutting edge technology to local middle school students and allow them to explore the world of nanoscience in real-time. The MRSEC graduate students with the help of an education outreach program from the FEI, electron microscopy company were able to bring a portable scanning electron microscope (SEM) into the classrooms of local middle schools.
